Comets necessarily obey the same physical laws as every other object. ... If one considers only two bodies -- either the Sun and a planet, or the Sun and a comet -- the smaller body appears to follow an elliptical path or orbit about the Sun, which is at one focus of the ellipse. ... Another quantity that is conserved is called angular momentum. ... Comets simply are bodies which in general have more angular momentum per unit mass than do planets and therefore move in more elongated orbits. ...

... Pierr Simone Laplas.) For his bright intellect and an outstanding achievements in several sciences (astronomy, physics, mathematics) Laplas was called "a French Newton". He became a consistent follower of Newton and rut a task before himself of explaining the planets motion, the movement of their satellites, the ocean rising tides in the Earth and a complicated motion of the Moon. Laplas showed that the planets inequalities should be periodical (based on Newton's gravitation principal). ...
